摘　　要：为在车辆自组织网络通信过程中公平使用有限的节点能量和网络带宽资源,提出一种动态负载均衡优化的AODV路由协议,即DLB-AODV路由协议。以无向图模型为基础,计算各节点的能量消耗和未使用带宽;在此基础上,设计动态负载均衡策略,依据路径传输数据耗费的总能量选取合格路径,依据路径拥有的最小未使用带宽对合格路径进行排序;在有序的多路径上分块传输消息。仿真结果表明,与EM-AODV和EN-AODV路由协议相比,该路由协议在报文送达率、端到端平均延时、节点能量消耗和可靠性4个方面具有明显优势。To use limited energy resources and network bandwidth equally in the process of vehicle Ad Hoc networks communications, an optimal AODV routing protocol with dynamic load balancing was proposed, called the DLB-AODV routing protocol. The energy consumption and unused bandwidth of each node based on undirected graph model were calculated. On this basis, a dynamic load balancing strategy was designed, which selected qualified paths according to the total energy used to transmit data, and these paths were ordered in terms of the minimum unused bandwidth. Messages were chunked transmitted on the orderly multiple paths. The simulation results show that, compared with EM-AODV and EN-AODV routing protocols, the proposed routing protocol has obvious advantages on four aspects including packet delivery rate, average end to-end delay, energy consumption and reliability.
